Director of User Acquisition

Fizz is the hottest Gen Z social platform in the world. Having started as America’s biggest college social app, Fizz is now allowing Gen Z globally to connect around their shared experiences and identities. College Fizz communities feature a private, moderated feed of posts from verified students, making it the most entertaining and authentic way to experience student life. Our newest product, Global Fizz, brings together all of Gen Z both domestically and abroad, providing a space to satisfy the 99% of life not on entertainment platforms like Instagram and TikTok. Fizz is on a mission to bring social back to social media.

We first launched Fizz at Stanford in July 2021 and have since seen >95% of undergraduates join the app, half of which use Fizz every day. Since raising a $25M Series B in July 2023, we have established ourselves as the dominant social app at 700+ colleges, have begun to generate revenue through advertising, and are actively expanding to communities beyond college. Most recently, Fizz hit #1 overall on the App Store charts in Saudi Arabia.

We have three primary goals for 2026: continue our expansion to the entire US college market, drive revenue growth through our revolutionary ads business, and rapidly expand to non-college students — both domestically and abroad. This role is central to that third goal.

We're looking for a Director of User Acquisition to own and scale Fizz's paid growth engine as we expand beyond college campuses into the broader US market and internationally. This is a builder role — you'll be an early hire for our performance marketing team, setting strategy, standing up infrastructure, and running campaigns hands-on.

You'll sit at the intersection of marketing, product, and data. You understand that great performance marketing isn't just about CAC — it's about finding the right users, in the right markets, at the right moment in their lives, and then using product and retention data to validate that the growth actually worked.
